Ack.
I do wonder if it should be marked somehow as being that special case.
The main reason for 'show_token()' is debugging, after all, and
TOKEN_ZERO_IDENT does have magical properties in how it either
silently expands to the constant '0', or it generates a warning about
undefined preprocessor symbol.
But considering that we've apparently reported it as "unhandled token
type '4'" since 2005, I guess it's not exactly a big deal.
